Disposal of radioactive waste from nuclear weapons production and power generation has caused public outcry and political consternation. Nuclear Wastes presents a critical review of some waste management and disposal alternatives to the current national policy of direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for what the nation should do today and what solutions should be explored for tomorrow. The committee examines the currently used "once-through" fuel cycle versus different alternatives of separations and transmutation technology systems, by which hazardous radionuclides are converted to nuclides that are either stable or radioactive with short half-lives. The volume provides detailed findings and conclusions about the status and feasibility of plutonium extraction and more advanced separations technologies, as well as three principal transmutation concepts for commercial reactor spent fuel. The book discusses nuclear proliferation; the U.S. nuclear regulatory structure; issues of health, safety and transportation; the proposed sale of electrical energy as a means of paying for the transmutation system; and other key issues.

The largest volumes of radioactive wastes in the United States contain only small amounts of radioactive material. These low-activity wastes (LAW) come from hospitals, utilities, research institutions, and defense installations where nuclear material is used. Millions of cubic feet of LAW also arise every year from non-nuclear enterprises such as mining and water treatment. While LAW present much less of a radiation hazard than spent nuclear fuel or high-level radioactive wastes, they can cause health risks if controlled improperly. Improving the Regulation and Management of Low-Activity Radioactive Wastes asserts that LAW should be regulated and managed according to the degree of risk they pose for treatment, storage, and disposal. Current regulations are based primarily on the type of industry that produced the waste-the waste's origin-rather than its risk. In this report, a risk-informed approach for regulating and managing all types of LAW in the United States is proposed. Implemented in a gradual or stepwise fashion, this approach combines scientific risk assessment with public values and perceptions. It focuses on the hazardous properties of the waste in question and how they compare with other waste materials. The approach is based on established principles for risk-informed decision making, current risk-informed initiatives by waste regulators in the United States and abroad, solutions available under current regulatory authorities, and remedies through new legislation when necessary.

Hazardous waste in the environment is one of the most difficult challenges facing our society. The purpose of this book is to provide a background of the many aspects of hazardous waste, from its sources to its consequences, focusing on the risks posed to human health and the environment. It explains the legislation and regulations surrounding hazardous waste; however, the scope of the book is much broader, discussing agents that are released into the environment that might not be classified as hazardous waste under the regulatory system, but nonetheless pose substantial hazards to human health and the environment. It provides a background of some of the major generators of hazardous wastes, explains the pathways by which humans and wildlife are exposed, and includes discussion of the adverse health effects linked to these pollutants. It provides numerous case studies of hazardous waste mismanagement that have led to disastrous consequences, and highlights the deficiencies in science and regulation that have allowed the public to be subjected to myriad potentially hazardous agents. Finally, it provides a discussion of measures that will need to be taken to control society’s hazardous waste problem. This book was designed to appeal to a wide range of audiences, including students, professionals, and general readers interested in the topic. Provides information about sources of and health risks posed by hazardous waste Explains the legislation and regulations surrounding hazardous waste Includes numerous case studies of mismanagement, highlights deficiencies in science and regulation and discusses measures to tackle society’s hazardous waste problems

Safety and environmental impact is of uppermost concern when dealing with the movement and storage of nuclear waste. The 20 chapters in 'An Introduction to Nuclear Waste Immobilisation' cover all important aspects of immobilisation, from nuclear decay, to regulations, to new technologies and methods. Significant focus is given to the analysis of the various matrices used in transport: cement, bitumen and glass, with the greatest attention being given to glass. The last chapter concentrates on the performance assessment of each matrix, and on new developments of ceramics and glass composite materials, thermochemical methods and in-situ metal matrix immobilisation. The book thoroughly covers all issues surrounding nuclear waste: from where to locate nuclear waste in the environment, through nuclear waste generation and sources, treatment schemes and technologies, immobilisation technologies and waste forms, disposal and long term behaviour. Particular attention is paid to internationally approved and worldwide-applied approaches and technologies. * Each chapter focuses on a different matrix used in nuclear waste immobilisation: Cement, bitumen, glass and new materials. * Keeps the most important issues surrounding nuclear waste – such as treatment schemes and technologies, and disposal - at the forefront.

How can nations ensure that buried nuclear waste goes undisturbed for thousands of years? The United States government tried to solve this problem with the help of experts they identified in communication, materials science, and futurism. From the perspective of a contemporary archaeologist, The Future of Nuclear Waste looks at what these experts suggested, and what the government endorsed: designs for a modern monument, an artificial ruin, a purpose-built archaeological site that would escape future exploration. One design, selected for development, argued that because specific archaeological sites and objects (among them Stonehenge, Serpent Mound, the Rosetta Stone, and rock art) made long ago have endured and are seen as significant today, contemporary engineers could build monuments that would be equally effective in conveying messages that last even longer. An alternative proposal, which government planners set aside, was rooted in the idea that universal archetypes of design arouse similar human emotions in all times and places. Both proposals used common sense, assuming that human reactions and understandings are relatively predictable. Employing an anthropology of common sense, Rosemary Joyce explores why people chosen for their expertise relied on generalizations contradicted by the actual history of preservation and interpretation of archaeological sites and the closest analogues to archetype-based designs, which are the large scale installations produced in the Land Art movement. The book reveals the underlying imagination shared by the experts, government planners, and artists, in which the American West is an empty space available for projects like these. It counters this with the dissenting voices of indigenous scholars and activists who document the presence on these nuclear landscapes of Native American people. The result is an eye-opening and unique demonstration of how a deep understanding of the remote past informs critical debates about the present.
